Abstract

We report the results on the growth, structural and optical characterization of single wurtzite (WZ) GaAs nanowires as well as WZ GaAs/AlGaAs core-shell nanowires with ZB GaAsSb inserts. For the GaAs/GaAsSb heterojunction both the crystal material and crystal phase change plays a critical role in the exact band alignment. We show that ZB GaAsSb inserts with both WZ and ZB GaAs barriers can be grown and hence both type I and type II band alignment can be achieved which has large effects on the optical properties of the nanowires. We thus demonstrate that it is possible to engineer the band-structure at a semiconductor heterojunction by modulating the crystal material as well as the crystal phase.
